DAVID A. J. LAMSON, OF CHERRY VALLEY, MASSACHUSETTS.

BELT-TOOL.

Specification of Letters Patent No. 18,206, dated September 15, 1857.

To all whom "it may concern: Be it known that I, D. A. J. LAMsoN, oCherry Valley, in the county of Leicester and State of Massachusetts,have invented a new and useful Combination-Tool for Mecha-nies andOthers; and I do hereby declare thatA the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure l, is a face view of the tool as in condition for being used as apunch or wrench. Fig. 2, is a similar view of the tool as in conditionto be used as a screw driver.

The nature of my invention consists in the combination of the severaltools herein specified, in one instrument, when constructed andoperating as hereinafter described.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

A, A, represent two levers pivoted together at B.

On one of the short ends or nipper jaws C, of these levers a hollowpunch E, is formed, and on the other end or nipper jaws C, a socket E',is provided to receive the punch, and thus allow of the jaws comingclose together when the tool is not in use, or when it is desired tobring the jaws together, and make the tool serve the office of nippers;which office is served by the portion b, b, of the short ends or jaws.

D, D, are V-shaped notches cut on the inner edge of the short ends orjaws, between the pivot B, and the punch E, and socket E. These notcheswhen brought together, by the closing of the jaws, form a square or foursided wrench.

On the inner edge of each of the long ends A, A, of the levers A, A, aV-shaped notch L, is cut, these notches when brought together form asquare or four sided wrench.

Beyond these notches in the inner edge of each of the long ends A', A, achamber or oblong recess K, is made. At the back of these chambers orrecesses K, K, a thin elliptic spring z', is arranged.

G, H, represent two implements fitted in these chambers or recesses; G,being a screw driver, and I-I, an awl. The screw driver and awl haveeach a shoulder J, formed on it and are pivoted at c, c, to theextremity of the long ends A', A, of the levers.

By examining the drawing Fig. 1, it will be seen that the chambers orrecesses K, K, are of corresponding form with the tools and thus receivethe shoulders J, J, snugly. It will also be seen by examining Fig. 2,that when the screw driver is thrown out, the shoulder of 1the samerests upon the shoulder of the awl, and vice versa when the awl isthrown out, and thus a firm stop or support is secured to the screwdriver or awl, and all chance of the same closing into its socket whilein use prevented.

This combination tool meets the wants of the factory, machine shop,store, hotel, oiiice and the household, and will be a great convenienceto mechanicians who travel from city to city repairing clocks and doinglight job work.

I-Iaving thus described my invention I will now state that I do notclaim broadly the combination of a number of implements together so asto form a complex or universal tool, irrespective of the constructionand arrangement of the parts forming such a tool, but

What I do claim as my invention and desire to secure by Letters Patent,is

The combination of the several tools herein specified in one instrument,when constructed and operating substantially as herein described.
